if you are adding two fractions that are both greater than 1/2 what must be true about the sum? Give three examples to support y
Sunny_sXe [5.5K]

Answer:

If you are adding to fractions that are both greater than 1/2, the sum will be greater than 1.

Step-by-step explanation: 1/2 + 1/2 =1    

Since both fractions are greater, obviously the sum will too.

Examples: 2/3+3/4= 1 5/12        4/6+6/9= 1 1/3

Hope this helps

Henry counted units to find the distance between two points. For which pair of points could he have done this? Select all that a
zimovet [89]

Answer: point

(5, 3) and (9, 3) (2, 3) and (7, 3)

Step-by-step explanation:

When all the coordinate are plotted on a graph, point (5, 3) and (9, 3) , & point (2, 3) and (7, 3) are found to be in a straight line. So Henry will count some units to find the distance between two points of the coordinate given above.

deff fn [24]

Using the above conditions ; If m ∠LOM = m ∠JKI,  if m ∠MON = m ∠IKH it is proved below that m ∠LON = m ∠HKJ as are congruent angles.

<h3>What are congruent angles about?</h3>

An angle is known to be Congruent if its angles do have equal measure."

Note that question, In the said figure of the angles (image attached),

m ∠LOM = m ∠JKI  (congruent angles)              taken as 1      

m ∠MON = m ∠IKH  (congruent angles)             taken as 2  

The one should sum up both the side angle  of m ∠MON in (1) we obtain;

m ∠LOM + m ∠MON = m ∠JKI + m ∠MON

Then one should replace angle  m ∠MON = m ∠IKH from (eqn. 2)  on right hand side and then it will be:

m ∠LOM + m ∠MON = m ∠JKI + m ∠IKH      taken as (3)

Then:

m ∠LOM + m ∠MON = m ∠LON  ( M is said to be the interior point of ∠LON)    taken as (4)

Since m ∠JKI + m ∠IKH = m ∠HKJ  ( I is said to be the interior point of ∠HKJ)            taken as number (5)

Using Number (3) , (4) and (5)  in the image attached, we obtained:

m ∠LON = m ∠HKJ  (Congruent angles)

Therefore, Using the above conditions ; If m ∠LOM = m ∠JKI,  if m ∠MON = m ∠IKH it is proved below that m ∠LON = m ∠HKJ as are congruent angles.
